Quantum teleportation is the fundamental communication unit in quantum communication.
Here, a three-level system is selected for storing and transmitting quantum information, due …

The learning of fundamental quantum properties—namely coherence, discord, and
entanglement—benchmarks the security, computational, and metrological capability of noisy …

We provide an adaptive learning algorithm for tomography of general quantum states. Our
proposal is based on the simultaneous perturbation stochastic approximation algorithm and …

We analyze the entanglement-based optimal parameter estimation protocol of Pauli channel
under noise. Specifically, we consider that the prepared probes undergo depolarizing noise …

The presence of quantum noise during parameter estimation reduces precision in the
estimate to sub-Heisenberg scaling. Ancilla-assisted bipartite entangled probes generally …

Hedge maximum-likelihood estimation (HMLE) overcomes the problem of the rank deficient
state which is present in maximum-likelihood estimation. HMLE is the quantum version of …
